Looks like there is no test with enabled ASAN

[void234]

Bug description

There is a bug (tarantool/tarantool#3069, fix has not been merged yet) and it is not detected by CI. It is detected when test-run.py is launched manually when Tarantool is built with ASAN enabled.
I suggest launching it with "ASAN_OPTIONS=detect_leaks=0 test/test-run.py" - LeakSanitizer detects a lot of issues with existing tests.

• OS: Linux
• OS Version: Ubuntu 20.04
• Architecture: amd64

Tarantool 2.8.0-40-g6bd3663d9
Target: Linux-x86_64-Debug
Build options: cmake . -DCMAKE_INSTALL_PREFIX=/usr/local -DENABLE_BACKTRACE=OFF
Compiler: /usr/bin/cc /usr/bin/c++
C_FLAGS: -fexceptions -funwind-tables -fno-common -fopenmp -msse2 -std=c11 -Wall -Wextra -Wno-strict-aliasing -Wno-char-subscripts -Wno-format-truncation -Wno-gnu-alignof-expression -fno-gnu89-inline -Wno-cast-function-type -Werror

Steps to reproduce
Run CI

Actual behavior
base64 decoder bug (#3069) is not detected

Expected behavior
base64 decoder bug (#3069) should be detected

It seems, we should determine 'asan clean' set of tests and run them regularly. (And file issues for tests known to be 'asan dirty', maybe with some meaningful grouping). At least we can start with unit tests if others are mostly broken with ASAN.

NB: CI workflow.

I suggest launching it with "ASAN_OPTIONS=detect_leaks=0 test/test-run.py" - LeakSanitizer detects a lot of issues with existing tests.

we run tests with ASAN_OPTIONS and LSAN_OPTIONS, see https://github.com/tarantool/tarantool/blob/master/.travis.mk#L202-L221:

test_asan_debian_no_deps: build_asan_debian
        ASAN=ON \
                LSAN_OPTIONS=suppressions=${PWD}/asan/lsan.supp \
                ASAN_OPTIONS=heap_profile=0:unmap_shadow_on_exit=1:detect_invalid_pointer_pairs=1:symbolize=1:detect_leaks=1:dump_instruction_bytes=1:print_suppressions=0 \
                make LuaJIT-test
        # Temporary excluded some tests by issue #4360:
        #  - To exclude tests from ASAN checks the asan/asan.supp file
        #    was set at the build time in cmake/profile.cmake file.
        #  - To exclude tests from LSAN checks the asan/lsan.supp file
        #    was set in environment options to be used at run time.
        cd test && ASAN=ON \
                LSAN_OPTIONS=suppressions=${PWD}/asan/lsan.supp \
                ASAN_OPTIONS=heap_profile=0:unmap_shadow_on_exit=1:detect_invalid_pointer_pairs=1:symbolize=1:detect_leaks=1:dump_instruction_bytes=1:print_suppressions=0 \
                ./test-run.py --force $(TEST_RUN_EXTRA_PARAMS)
